GLASS-TREATING PACKET.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed. October 2, 1919. Serial No. 328,080.

To all whom it may conccrnr.

Be it known that I, ALBERT L. CLAPP, a citizen of the United States, residing at Marblehead, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Glass-Treating Packets, of which the following is a specification.

The object of this invention is to provide a book or packet containing detachable. leaves or sheets which may be utilized in treating glass so that it will not become clouded with condensed moisture.

The invention consists of a book or packet in which the leaves or sheets are detachable, and which are treated with glycerin or like materi 1 so that they may be used to rub the glass portions of a wind shield, eye glasses,

*indow panes, or the like, to prevent their becoming clouded or covered with condensed iois'ture. Preferably the leaves are secured within a cover of material which will not be affected by the glycerin, such, for example, as oiled or waxed paper.

On the accompanying drawings,

Figure 1 illustrates a book or packet embodying the invention.

Fig. 2 represents a perspective view of the same with the cover open and one of the leaves or sheets partially detached.

The sheets, which constitute the leaves of a book, consist of parchment paper saturated with glycerin. In practice the paper is passed through a heated bath of lycerin and water in the proportion of approximately of glycerin and 75% of water. After being saturated with the mixture of water and glycerin, the paper is dried, and, when dried, it will be found to have absorbed ap proximately 100% by weight of glycerin. In drying, the paper is preferably passed over a heater so as to expedite the evaporation of the water. The sheets thus dried may be cut into any convenient size, say for example, et inches by 41} inches, and each sheet is perforated along a line near its inner edge. As illustrated upon the drawing, one of the sheets is indicated at a, and it like the others is provided with a line of perforations indicated at b. Any suitable predetermined number of the sheets are arranged in a pile, and they are bound within the cover 0 as by the use of staples (Z d driven through the cover and through the sheets. The cover, as stated, is preferably made of fairly heavy paper such as Manila paper, which is relatively thick and is waxed 0r oiled in any approved way so that it will not soil the pockets or clothing of the user.

I am quite aware that it is not new to saturate a cloth with glycerin for the purpose of treating glass, but, so far as I am aware, I am the first to have provided, as a new article of manufacture, a book or packet provided with detachable paper leaves or sheets treated with glycerin or equivalent material for the purpose stated.

Having thus explained the nature of my mg and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim is:

1. As a new article of manufacture for treating glass, a book or packet consisting of a plurality of detachable leaves or sheets bound together and impregnated with glyc- Gl'ln.

2. As a new article of manufacture for treating glass, a book or packet consisting of a plurality of detachable paper sheets or leaves, each impregnated with glycerin, and a cover inclosing said packet to prevent contact wi h the impregnated leaves or sheets.

In testimony whereof I have affixed my signature.
